The scaling clause is almost decorative: whether you surveil for two or for eight, the three cards drawn are the entire payload, and no artifact deck is spending five mana at instant speed to bin one extra land. That is the design tension worth sitting with. Blue has always priced its instant-speed card advantage carefully, and the standard rate for drawing three at instant speed sits below five mana; this attaches the surveil-X rider as a sweetener rather than the reason to run the card, which inverts what the name and the artifact count imply. The surveil resolves before the draw, so the filtering happens first: you can send a spent artifact or a graveyard payoff to the yard and still refill your hand behind it. That ordering only earns its keep if you have artifacts on the battlefield and something waiting to do with what you mill. Absent both, this is a fair blue draw spell wearing an artifact-matters costume, holding open a counterspell window on an opponent's turn or refueling at end of turn. The card that cares about artifact count and the card that draws three want to live in different decks; the seam between them is the wrinkle to reckon with before the rate justifies the slot.
